In step S58, controller 80 cuts out first dump valve 46, makes discharge path 76 form full-shut position.Finish air thus and eliminate operation.
After air is eliminated the operation end, then, carry out coating filling work procedure to coating material cartridge 1 filling paint.As shown in Figure 5, controller 80 makes and triggers valve 72 actions (step S72), and make coating feed path 70 and be coated with flow path 14 and be communicated with, and disconnection coating feed path 70 and discharge path 76.Thus, coating is filled in the box bag 3 of coating material cartridge 1.Controller 80 is opened first and is squeezed liquid valve 62a (step S74).Importing in box bag 3 after coating makes that the volume of box bag 3 increases, extrude liquid and air in the coating material cartridge 1 flow into first and extrude liquid and discharge in the road 62.Extruding liquid extrudes liquid by first and discharges road 62 and be directed to and extrude in the flow container 68.
The coating that passes out to the coating feed path 70 from paint can 22 passes through in the coating feed path 70 at a high speed.Thus, shortened the filling paint required time.Air in coating feed path 70 is eliminated in the operation, and the coating by coating feed path 70 is imported in the discharge path 76 at high speed.Being directed to coating in the discharge path 76 can not be filled in the coating material cartridge 1 and become useless coating.In coating material charging device 10, dispose coating sensor 42 in the position near triggering valve 72 of discharge path 76.Thus, in coating material charging device 10, the coating that is directed in the discharge path 76 is detected by coating sensor 42.After coating sensor 42 detects coating, close first dump valve 46 by controller 80, sealing discharge path 76.Thus, stop to import coating, can reduce useless coating content to discharge path 76.
For example, can not detect under the situation of coating because of coating sensor 42 is damaged, even the air of coating feed path 70 eliminate finish, coating arrived discharge path 76, coating sensor 42 also detects less than coating.Perhaps, remaining in coating feed path 70 have coating, and before the coating of supplying with from paint can 22 arrived discharge path 76, coating sensor 42 had detected remaining coating.Finish air in this stage and eliminate operation, meeting air pocket in coating feed path 70.In this coating material charging device 10, even be under state that can not detect coating or the state that detects coating mistakenly, also can close first dump valve 46 by timer 66 at coating sensor 42, make discharge path 76 form full-shut position.Thus,, also can eliminate the air in the coating feed path 70 reliably, and suppress useless coating content even coating sensor 42 takes place to detect condition of poor.
In above-mentioned, to eliminate in the operation at air, coating passes through at a high speed in discharge path 76.Thus, expect and close first dump valve 46 detecting from coating sensor 42 to be coated with, make in the process till discharge path 76 forms full-shut position, still have coating and import in the discharge path 76.In this coating material charging device 10, eliminate in the operation at air, by second dump valve 44 discharge path 76 is sealed partly.Device company, the discharge path 76 that the air of being extruded by coating can be closed by the part swimmingly.On the other hand, flowing of coating hindered by the discharge path 76 of partial closure.That is, the flow velocity that flows through the coating of discharge path 76 is lowered.Thus, can reduce detecting and be coated with the coating content that imports to the process of expecting till closing first dump valve 46 in the discharge path 76 from coating sensor 42.
In Fig. 6, show and under partial closure's state of second dump valve 44, make aperture area (aperture area during the relative partial closure state of the aperture area during with standard-sized sheet) change the result that the flow velocity of the coating behind second dump valve 44 compares is flow through in the back to change figure.
The ratio of the transverse axis of Fig. 6 aperture area of the discharge path 76 during with respect to standard-sized sheet for the aperture area of the discharge path under partial closure's state 76.The ratio of the longitudinal axis of Fig. 6 coating flow in the unit interval during with respect to standard-sized sheet for the coating flow in the unit interval under partial closure's state.As shown in Figure 6, the ratio of the aperture area when making aperture area under partial closure's state with respect to standard-sized sheet is 10%, be 1/10 when following of aperture area under the partial closure's state aperture area when being standard-sized sheet, below half of the coating flow in the unit interval in the time of can making coating flow in the unit interval under partial closure's state be standard-sized sheet.That is, below 1/10 of aperture area when making aperture area under partial closure's state be standard-sized sheet can more effectively reduce the flow velocity of the coating in the discharge path 76.
